(oral- 91) 4 Claims.

The invention :relatesto the bandingofi pack-a ages of sheet'steel or other materials, andmore. particularly .to .a machine gforq sealing: the steelbands or straps with which the paekages are bound."

Sheets of steel are usually-shipped,-from'themill in packages or bundles. bound; Withf-steel: bands orstraps the ends-of. which are connected together by sheet metal--seals W The steel bandsv maybe stretched-around the, bundle or package; of: sheets; or; the like, byga y' suitable banding 'machine which may ibe of' thetype shown in my Patent No. 2,247,398-;;:dated July 1, 1941, by means of which the bands: are strapped tightly around the bundle-with the ends of the band overlappedet receive-sheet metal: seals which are usually.cr-imped;upon.the o ler-v lapped ends of thebandsto; hold-them tightly. bound around the package. 2; .i.

Under present practice,-ethis..sealingeis per-: formed byma deviceknown i-n-.tl 1e trade asaseal-s ing machine. Such sealing machlnesas are now.- in general useare. large, heavy; anal-cumbersome; and require both hands; to: operate the; same; making it necessary for I onet-man touoperate the. banding machine to stretchqa band-around the. package while another-man is required to operate; the sealing machine;

Another objection 'toi such sea-ling machines .-as are now in useisrdue-totherfact thatabecause of the manner iniwhicnsuchamachinesiare con structed it is very; difficultto crimpzth t seal where the bands and-seaLare flattened; tightly against the p k e. of sheets or. other:materialetolmbe banded. This islar ely due @to; the fact that under present practice the sea1ing-.;machines;im

use are designed to crimpworwcut theaseale and;

bands downward against theipackage; r I g It is an object of. thepresent invention to pro;.

vide a hand sealingi- -machinexof comparatively. lightweight and so constructed that -it ;!r,1ay.he

operated with one hand while the-operaton uses.

the other hand to. stretch the; bandwith a band=-1 ing machine or. tool, V

Another object of the invention is the-provision of. a band sealingmachine ;which cuts the-$83 1;

and band upward, whereby. itlmaybe entered:

under the edges of. a sea ardless of how tighhei ly the band may be stretched around the packa' eq A further object isthe provision ofi; such-, a

band sealing machine in whiel i the cuttinged-ges; are carried upon pivoted jaws arrangeditogengag e beneath the seal zindband,

which the pivoted jaws are operated throughv toggleleversbya single openating handle onlever.

Still another object is the .provisiontof alband sealing machine of thea type referljed to, in which; a central die rtion is provided? for clamping and mashing the 3 central portion of theseahand adjacent. portions of the; bandwdownward du r-r.

For this purpose each jaw mayhave an inwardly'disposedfbos's20 fitted within a curved recess 2| in the corresponding side of the block H and hav-- inga bearing opening 22 receiving the adjacent bolt l8 upon which the jaw is pivoted.

f'E'Iach' jaw 19' hasapair of cutting knives 23 preferablyformedupon the pins 24 received in suitable openings 25in the jaws. The cutting edge portion 'of each of these pins is located withinan angular lateral recess 26 in the inner face of the 'jaw,'terminating at its lower end in thetapered inwardly disposed'lip 21. The cutting e'dges' 23a,-o f these cutting knives, diverge upwardlyi'from the lips 21 of the jaws, as shown quite clearly in Fig: 3, and each knife has a-b'evelled outer face'fl, as best'shown in Figs. 6 and 7. An u'pwardlyf disposed lever portion 28 is fo'rrrie'dupon eacn'jaw and provided with spaced notches 23 at its upper end for-receiving the ad jace'nt ends ofj the toggle levers 30 which are pivotallyconnected to' the levers 28' as by the 7 pins 3|". The opposite'ends of the'toggle levers 3 llare, received between the discs 32 and 33 to. which'they are'pivotally connected as by-the' pins 34.

The discs 32 and 33 are mounted in spaced.

relation upon a bushing 35 fixed upon the shaft 36 which is journaledin the'u'pper portions of the 'side platesl2 and provided at each end with a'nut' or head 36. The discs 32 and 33 are preferably rigidly connected together as by pin 31, and the operating handle or lever38 is fixedto thegcentral disc 32 so that movement of said handle'from'the raised position'as shown inFig,

I tothe lowered position as shown in Fig, -3 will cause the jaws l 9" to beswung toward each other --In forming a package-of'sh'eets or the lik one 7 upon theirpivots l8."

or more sheet metal band s'or" str'aps as indicated at'39may be placedarou'nd the package with the overlapped ends thereoi inserted through a sheet metal seal 40 and the band 'i's dr'awn tightly" aroundthepack by any suitableflform of; handing machine or tool. a

I The sealing machine is then placed over the seal 40 in the position shown in" Figs. 1 and 2, the central flanged portion of the block llfrestlng upon the central portion of-theseal 40, The

rigid arm l1 rests up'on' -the top; of the package being banded, holding the e'aling' machine} in vertical-position While the workmm operates the banding m:

"like.

chine with one hand to stretch the band tightly around the package, with the other hand he pulls portion of the seal downward between said cuts,

a indicated at 44 The band is thus held tightly strapped ,1 around the package and cannot be removed unless it is severed as by shears or the From: the above it will be evident that the improved sealing machine is simply and easily operated, being of such light weight and so constructed that it may be operated by one hand, leaving'the other hand free to operate the bandingmachine or tool.

It will also be seenthat the machine will work efiiciently to quickly and easily seal a band even thoughthe same may bestretched tightly against thesurface'of the package, asthe tapered lips 2'! of the jaws engage under the edges of the seal and the cutting edges 23a cut the seal and band upward while the block H holds the control portion of the seal'and band down toward thev package;
